These are fab basses.
This is a B2, Ash body I believe, maple neck, rosewood board, made in Japan in the 90's.
Separate treble & bass pots, volume and balance.
Then trim pots in the cavity.
I play a B4, with ebony board, super jazz bass to play, loads of tonal options.
These tend to go under the radar.
My B4 is quite heavy though Ash
